What are Tower Defense RNG codes used for?
In Tower Defense RNG, Rubies and Onyx are important late-game currencies used to improve and optimize your towers.
Rubies are spent on rolling tower traits and removing decay, while Onyx is used to reroll augments in search of stronger bonuses. Since both are rare to earn naturally, codes are useful because they can grant free Onyx along with luck and roll speed boosts, helping you progress more consistently.
